Abstract: The use of recycled concrete aggregates as an alternative aggregate material in concrete has been studied over the past two decades. It is now recognized that the recycled aggregate concrete (RAC), where natural aggregates ...

Abstract: A novel self-centering (SC) tall-pier bridge system is proposed to improve the seismic performance of tall-pier bridges (pier height >40  m). The system features tall piers with unbonded post-tensioned (PT) tendons at ...

Abstract: Knowledge of shear friction material properties is central to the design of reinforced concrete elements. These shear friction properties are impacted by components of concrete mix design that impact the roughness of a ...
